there is a good chance that the "measurement" is recording some other phenominon, as this can only be an interpretation of albedo changes, and could be the signal from say, low orbiting small moons or a planetary ring,atmospheric electrical discharges in any case, it is most definitly not an actual wind speed measurement, plus strictly speaking "wind" can only happen in air, and this, again, can only be something else, with the use of the term "supersonic" not even remotly applicable, unless of course its of the football field per second type of calculation standard

This isn't measurement of albedo changes. It's measurements of spectra that exhibit Doppler effect, which permits measurement of wind velocity. From the abstract: "We studied the transmission spectrum of the hot Jupiter WASP-127 b during one transit in the K band with CRIRES+." They acquired spectra for H2O and CO with hi-res transmission spectroscopy as the planet transited its star. https://www.aanda.org/articles/aa/full_html/2025/01/aa50438-24/aa50438-24.html https://www.aanda.org/articles/aa/full_html/2025/01/aa50438-...
